An overview of the Apache Solr search server, including upcoming features such as geo-aware searching.

Apache Solr is a state of the art, high performance and scalable search server you can use in your (PHP) application to provide a very feature rich search experience. Besides full-text search, it also provides spell checking, highlighting, facets and powerful functions that can put it in the realm of a general information retrieval engine, replacing complex database queries you would (need to) use otherwise.
